Answer:

Answer is 13.

Step-by-step explanation:

EQ 1: y = 2x^2-x-2  

EQ2: y = x^2+3x -5

Set the two equation equal to each other:

2x^2-x-2 = x^2+3x -5

Simplify:

x^2 -4x +3 = 0

(x - 3 ) (x - 1) = 0

Solutions:

x = 3 and x= 1

Plug these values into each of the original equations and see which on gives you the highest value.

Solution set:

y={13, -1, 13, -1}

Answer is 13

(7,5), (r,9) m=6<br><br> What is r?
Igoryamba

Answer:

The answer is that r = 7/6

Step-by-step explanation:

Given point: (7, 5)

Given slope: m = 6

Use the point slope form of the equation:

y - y1 = m(x - x1)

y - 5 = 6(x - 7)

y - 5 = 6x - 7

y = 6x + 2

Now, find r for the point (r, 9) by substitution:

9 = 6x + 2

6x + 2 = 9

6x = 7

x = 7/6

Proof:

y = 6x + 2

f(x) = 6x + 2

f(7/6) = 6(7/6) + 2

= 42/6 + 2

= 7 + 2 = 9, giving (7/6, 9). r = 7/6

Hope this helps! Have a great day!
